Figure 5. Functional analysis of lamprey CNEs in zebrafish embryos.

Figure 5

A, LfHhb intron2 enhancer activity visualized in representative zebrafish embryos at 26hpf, at low (left) and high magnification (right) focusing on the notochord and floor plate. B, LfHhb ar-C1 enhancer activity visualized in two representative embryo at 26hpf, one at low (left) and one at high magnification (right) focusing on the notochord and floor plate. A schematic representation of the reporter constructs is shown in each case. It contains a zebrafish shha -0.8 kb minimal promoter driving GFP expression under control of the 3.1 kb intron2 (shown in A) or the 30 bp LfHhb ar-C1 (shown in B).
